Suicidal Ideation and Death by Suicide as a Result of the COVID-19 Pandemic in Spanish-Speaking Countries: Systematic Review.

Suicidal behaviors and constructs are putting at risk the accomplishment of Objective 3 of Agenda 2030 for sustainable development in Spanish-speaking countries. The current study's principal objective is to explain the presence of suicidal ideation and deaths by suicide as a result of the COVID-19 pandemic in Spanish-speaking countries based on a review of the scientific literature. The PRISMA model was used as the main method while considering the criteria of periodicity, language, typology, and country in order to choose the 28 articles that were analyzed from the following three databases: SCOPUS, Web of Science, and ProQuest Coronavirus Research Database. Suicidal ideation and death by suicide exhibited a growth trend during the COVID-19 pandemic, including post-pandemic, especially in kids, adolescents, and young women of university age belonging to lower socioeconomic strata and presenting risk factors like living in rural areas, poor mental health, unemployment, and family death due to COVID-19.

Multimodal technique to eliminate humidity interference for specific detection of ethanol.

Multimodal electrochemical technique incorporating both open circuit potential (OCP) and amperometric techniques have been conceptualized and implemented to improve the detection of specific analyte in systems where more than one analyte is present. This approach has been demonstrated through the detection of ethanol while eliminating the contribution of water in a micro fuel cell sensor system. The sensor was interfaced with LMP91000 potentiostat, controlled through MSP430F5529LP microcontroller to implement an auto-calibration algorithm tailored to improve the detection of alcohol. The sensor was designed and fabricated as a three electrode system with Nafion as a proton exchange membrane (PEM). The electrochemical signal of the interfering phase (water) was eliminated by implementing the multimodal electrochemical detection technique. The results were validated by comparing sensor and potentiostat performances with a commercial sensor and potentiostat respectively. The results suggest that such a sensing system can detect ethanol at concentrations as low as 5ppm. The structure and properties such as low detection limit, selectivity and miniaturized size enables potential application of this device in wearable transdermal alcohol measurements.

Salvamento del pie diabético / Salvatage for diabetic foot

Se revisaron 27 pacientes diabèticos con enfermedad arterial documentada por angiografía y pie diabètico infectado, en un periodo de 42 meses. Todos fueron manejados inicialmente con medidas de higiene venosa, desbridación de tejido desvitalizado e infectado, antibioticoterapia y control metabólico. La cirugía reconstructora siempre se realiza cuando las condiciones locales y generales han mejorado. En ningún paciente se realizó procedimiento vascular y reconstructor en forma simultànea. De los 27 pacientes: 8 se presentaron con exposición del dorso del pie (tendones y hueso), 5 con úlceras plantares, 5 con necrosis parcial de la punta de los ortejos, 3 con exposición de mal,olo y 6 con exposición de tibia y rodilla. Las cirugías incluyeron 3 colgajos de músculo gemelo, 3 fasciocut neos, 5 colgajos locales de piel y 27 injertos. No hubo fallecimientos. Como complicaciones hubo un paciente con lisis del injerto por candida, neoformación de úlceras en 3 ocasiones en un mismo paciente en nuevas àreas anatómicas, 3 pacientes con sepsis. El tratamiento combinado para reconstrucción de úlceras en extremidad inferior ha dado excelentes resultados en la mayoría de los pacientes.
